Hacktoberfest Hack Day Kota Batam x Batam Innovation Center
About
Join us for Hacktoberfest Hack Day Kota Batam x Batam Innovation Center, a one-day, in-person Hacktoberfest event organised with the support of Batam State Polytechnic, where participants will build with open-source or open-weight AI, submit through OrganizerHQ Challenges, and compete in the Best Open-Source AI Project challenge. Bring your laptop and your curiosity!
This hackathon is focussed on Google Gemma.
Google supports Major League Hacking and the Hack Days program with AI tools for experimentation and rapid prototyping. This category gives hackers a chance to build with Gemma, Google’s family of lightweight, open models.
Best Use of Gemma 4
It’s time to see how much you can build with a lightweight, open model. Gemma 4 packs multimodal intelligence into an open-weights model that you can access through the Gemini API. Gemma 4 can help you:
Work with text and images to create an assistant that understands more of what users share
Build a focused AI tool for learning, creativity, productivity, or your community
Experiment with an open model while using the Gemini API to move quickly from an idea to a working prototype.
Team size minimum 1 and maximum 2. Note that the MLH system does not handle team formation. Each team member will register individually and one of the two team members will submit the project
Bring your idea to life… what will you build with Gemma 4 today?
Happy hacking!
